Subscriber control unit for united home security system
First Claim
1. A security system for a plurality of subscribers, comprising:
- a) a security device located in each of the plurality of subscribers, each security device comprising;
i) a sensing circuit including at least one sensing element to generate a detection signal;
ii) an emergency handling/communication circuit including at least one alarm device; and
iii) a monitor/control server including a central processing unit connected to the serving circuit to receive generated detection signals and to the emergency handling/communication circuit the central processing unit having a dual tone multi-frequency signal receiver enabling the central processing unit to be connected to a public telecom network in response to a ringing signal transmitted through the public telecom network and to receive a dual tone multi-frequency signal transmitted over the public telecom network, a dialing circuit for performing an automatic dialing operation, and a radio frequency receiver;
b) a remotely located administrating and monitoring device connected to each of the monitor/control servers via the public telecom network to selectively communicate with the monitor/central servers; and
,c) a remote setting unit communicating with at least one monitor/central servers via radio frequency so as to control the operation of the at least one monitor/control server.

Abstract
A subscriber control circuit adapted to be incorporated in an united home security system is disclosed. The control circuit includes a plurality of client-side monitor/control servers, each serving to detect and control the situation at the subscriber and connected to a remote administrating and monitoring device via a public telephone network. The remote administrating and monitoring device is capable of transmitting alarm signal to an alarm transmitting network. The client-side monitor/control server also includes a central processing unit, a radio frequency receiver for receiving a detection signal from wireless sensing elements and an encoder for receiving and processing a detection signal from cabled sensing element. A DTMF based receiver connects the central processing unit to the remote administrating and monitoring device to receive a DTMF signal transmitted through the telephone line and transmit the received DTMF signal to the central processing unit. A dialer circuit is coupled to the central processing unit for performing automatic dialing operation.
